So this grep through my access logs for this single URL does a good job illustrating a rather interesting problem: $ grep -h 'https://static.licdn.com/sc/h/ddzuq7qeny6qn0ysh3hj6pzmr text/css

text/css ip_index=0,client=m0078269_9094 At first I thought this was because the because I have a bunch of clients, each of which behaves exactly the same except for one thing: the client includes a unique request header that squid strips off before forwarding to the server (you can see it logged as client=mXXXXX_XXXX). But in this case I've controlled for that and only grep'd for a single client's request. I've even tried setting "vary_ignore_expire on", but that doesn't seem to be a complete fix. I can't for the life of me understand why the low hit rate though. -- Aaron Turner https://synfin.net/ Twitter: @synfinatic My father once told me that respect for the truth comes close to being the basis for all morality. "Something cannot emerge from nothing," he said. This is profound thinking if you understand how unstable "the truth" can be. -- Frank Herbert, Dune _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
